Thanks, whenever I get those things and they break easily I am concerned they're not the metal they're claiming to be - but if it's process based it's not great but at least it's not something inherently dangerous

Yeah, it's just a simple way to make a part. Instead of fully melting and pouring to a mold you instead dump a powdered form of the metal into it and then use heat and pressure to not fully melt it, but heat it up to where the combined heat and pressure causes the particles to begin fusing. Relatively speaking it's quick, easy, takes less energy and so on. It is quite brittle, however, and not as strong in general since you don't get nice, long grains in the metal.
